Customizing Physiologic Alarms in the Emergency Department: A Regression Discontinuity, Quality Improvement Study

Area of Science:

• Healthcare Quality Improvement
• Patient Safety Technology
• Clinical Alarm Management

Background:

• Excessive clinical alarms lead to alarm fatigue, risking missed critical events.
• This project focused on reducing nonactionable physiologic alarms, not alarm fatigue itself.
• The Iowa Model guided the evidence-based practice project.

Purpose of the Study:

• To implement and evaluate a program reducing nonactionable physiologic alarms in an emergency department.
• To decrease the overall alarm burden on clinical staff.
• To enhance patient safety by addressing a key contributor to alarm fatigue.

Main Methods:

• Adjusted default alarm settings on physiologic monitors.
• Implemented a staff education plan on safe alarm use.
• Utilized a regression discontinuity design for pre- and post-implementation analysis.

Main Results:

• Achieved a statistically significant reduction in alarm events (14.96, P=0.003).
• No adverse patient outcomes, such as delayed response or cardiopulmonary arrest, were reported.
• Demonstrated the effectiveness of multimodal strategies in reducing alarm burden.

Conclusions:

• Multimodal strategies, including setting adjustments and staff education, effectively reduced nonactionable alarms.
• Improved alarm management enhances patient safety and reduces risks associated with alarm fatigue.
• Staff accountability is crucial for sustained improvements in clinical alarm management.
